HOLDING FRAME FOR EMBROIDERENG-MACHENES SPECIFICATION forming part of Letters Patent No, 388,035, dated August 21, 1888,

Application tiled June 16, 1886. Serial No. 205,302.

To (LZZ whom it may concern.-

3e it known that i, FRIEDRICH GEGAUF, a citizen of Germany, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Embroidering Machines and Attachments; and Idohereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in attachments for embroidering-machines, particularly those known as the Swiss embroideringmachines, to which, however, the application of the invention is not necessarily limited, and is designed to enablea large number of small patterns on separate pieces of mate rial to be embroidered on the same machine simultaneously.

The invention is further intended to be used outside of and independent from the said embroidering-machine as a hand embroideringframe, like an ordinary tambonrirame, both of which uses, however, will be more fully described hereinafter.

In the accompanying three sheets of drawings, in which similar letters of reference indicate corresponding parts, Figure 1, Sheet 1, is a front elevation of that portion of an embroider-irig-machine in which the material to be embroidered is arranged and which is caused to move or vibrate in front of the needles and of my attachment arranged therein. Fig. 2 is a side elevation of an embroidering orstretching frame and portions of its holding-strip detached from the vibrating frame. Fig. 3 is a section of Fig. 2 through line as. Fig. 4 is a perspective view of a stretching-frame and binding-clamps. Fig. 5is a transverse section of a stretching or embroidering frame and the material secured thereto. Fig. 6 is a crosssection of one side of the frame shown in Fig. 5, illustrating the manner of applying the binding clamps thereto. Fig. 7 is a side elevation of a modified form of bindingclamp. On Sheet 2, Figs. 8, 9, and 13 illustrate various forms of frames. Figs. 10 and 12 are front and end elevations, respectively, of a form of (No model) frame differing in cross -section from those above described; and Fig. 11 illustrates various cross-sections that may be used. Fig. 14 on Sheet 3 is a front elevation of an embroideringmachinc with which my improvement is adapted to be used.

Similar reference-letters are employed to indicate corresponding parts.

The special purpose for which this invention is designed when used in an eml'iroideringmachine is to enable a large number of patterns of varying sizes to be embroidered on separate pieces of cloth or other material instead of embroidering the patterns on a continuous piece of material wound on rollers, and wound and unwound as the designs are finished and a new surface is presented to the needles. This is particularly advantageous in embroidering handkerchiefs, patterns for slippers, &c., and all articles or garments that are embroidered after having been cut to a pattern or any desired sizeas towels, napkins, &c.

The portion of an embroidering-n1achine in which the improved attachment may be used (shown in Figs. 1 and 14) is a vibrating frame,

A, to which the material to be embroidered is suitably attached, and which, by the movement of said frame, is caused to present new surfaces to the needles. In said frame are arranged the fabrie-holding frames 13, which are placed close together between adjustable strips 0 (3, two pairs of which are shown in Fig. 1 one pair for each row of needles used in the Swiss machine. For ad j nsti ng said strips CC any suitable mechanical device may be employed, that shown in the drawings for illustration consisting of threaded rods 0, which extend from the top to the bottom of the frame A, as indicated, and through the strips, and are provided with nuts 0' above and below each strip, which, when turned, cause the raising and lowering of each strip as far as may be desired. The adjustability of the strips allows the in 5 sertion of embroideri ngfram es of d ifferent sizes therebetween in the same machine.

To secure the embroidcring-frames firmly between the strips, a groove, c, is provided in one of said strips and a recess, 0 in the other 1C0 of said strips, as indicated in Figs. 2 and 3, one end of the embroidering-framcs resting in the groove and the other end thereof being held in the recess by a pivoted arm, 0*. The frames are removed from the strips simply by turning the arm 0*, and are thereby free to be lifted from the groove and clear of the strips. To separate the frames when placed in position between the strips, I may employ projections 0 which prevent the frames from being displaced, as indicated in Fig. 2; but the frames may also touch and support one another without the intervening projections, particularly when frames of different widths are used.

In the drawings various kinds of embroidering-frames are shown, which may have three, four, or any number of sides, being triangular, quadrilateral, or polygonal in form or irregularly formed, Figs. 8 and 9, but all of which sides are preferably straight to allow of the application and proper operation ofthespringclamps d.

In cross section the sides may be of any form, either round, elliptical, slightly flattened, or angular, as at e, e, and c", Fig. 11, respectively, that shown at e in said figure being considered preferable because of the ease with which the binding-clamps (Z may be applied thereto and caused to bind the goods firmly to the frame.

In Figs. 4, 5, and 6 the method of applying the clamps to the embroidering-frame and of drawing the material to be embroidered tightly across the frame is illustrated, when the sides of the frame are formed in cross-section, like the form shown at c, Fig. 11. The clamps shown in said figures are formed from a continuous piece of spring metal bent substantially as shown, and, in applying the same to the stretching-frame, are pushed upon the frame from the sides over the fabric, as indicated in Figs. 4 and 6, and are then turned down at right angles to the first position, as in Fig. 5, the fabric f being stretched between the inner edges, (1, of the clamps.

The sides of the frame B being oval or elliptical in cross-section, as shown in Fig. 6, the clamps are readily pressed upon the same from the sides over the thin edges, and when turned down at right angles to the first position, the increased diameter of the oval sides causes the clamps to bind upon the frame and to hold the fabric securely upon said frame. This method of applying the clamps to the stretching-frame may also be used when the sides are angularly formed in cross-section, as at e", Fig. 11.

In Figs. 16 and 12 is illustrated a stretching-frame, the sides of which in cross-section are round, as at e, and the binding-clamps are applied thereto by being slid or pushed on the end of each side, as shown in Fig. 10.

As hereinbefore mentioned, the embroidering or stretching frames may be variously shaped quadrilaterally, as in Figs. 1 to 10, which form is especially adapted for embroidering the centers of handkerchiefs, &c.; or said frames may be irregularly formed, as shown in Figs. 8 and 9, and thereby adapted for embroidering the corners of handkerchiefs, &c.,

because. of the peculiar form. These irregular forms are advantageous in that when arranged side by side, as indicated in Figs. 8 and 9, in the vibrating frame a larger number of the frames may be inserted in the same space when thus irregularly formed than when quadrilaterally formed, the irregular forms fitting one into the other, as illustrated in said figures.

While the embroidering-frames herein de scribed are intended and adapted to be used in an embroidering-machine, still they may be employed as a hand embroidering frame. When designed for this purpose, any regular form of frame may be used, those previously described or the form illustrated in Fig. 13.

In Fig. 1 is illustrated a modified form of the binding-clamp, consisting of two pivoted sections, d d between which is arranged a spring, dflwhich provides the force necessary to bind the fabric upon the stretching-frames.

Having thus described and illustrated my invention, whatI claim is 1. A fabric-stretching frame provided with sides oval in cross-sections, in combination with binding-clamps having yielding jaws applied to the thin edges of said oval sides and turned at right angles thereto, so that said clamps bind the ends of the oval sides of said frame, for the purposes set forth.

2. The combination, in a vibrating 0r tambour frame, of pairs of grooved and recessed holding-strips adj ustably arranged in said frame,with threaded rods secured to said frame on which said holding-strips move, and holding-nuts arranged on said rods and engaging with the said holding-strips, substantially as and for the purposes set forth.

3. The combination, in a vibrating or tambour frame, of pairs of holding-strips constructed and arranged to hold a series of removable fabric-stretching frames, said stretching-frames projecting or fitting one into the other, and binding-clamps, whereby the corners of the fabric to be embroidered are held upon and stretched across said frames, substantially as and for the purposes set forth.

4. The combination,with a vibrating or tambour frame of an embroidering-rnachine, of pairs of adjustable holding bars or strips extending longitudinally in said frame, and constructed and arranged to hold a series of fab ric-stretching frames removable therein and to be moved toward and from each other, adjusting devices,whereby said pairs of bars are moved toward and from each other and are held rigidly in position when thus adjusted, and a series of fabric-stretching frames removably arranged between said holding-bars, for the purposes set forth.

In testimony that I claim the foregoing I have hereunto set my hand this 5th day of June, 1886.

FRIEDRICH GEGAUF.
